Answer:
slope: 5/7
0.714 mile per hour
Step-by-step explanation:
slope: find the point where the line is right on the line graph, put y/x which is 10/14 make the fraction smaller which is 10/14 = 5/7(I divide the denominator and nominator by 2)
Mile per hour: 5/7 cross multiply with x/1, make into an equation:
7x=5 x 1
7x = 5
x = 0.714
Answer: b. 0.8413
Step-by-step explanation:
Given : The average time taken to complete an exam, X, follows a normal probability distribution with and .
Then, the probability that a randomly chosen student will take more than 30 minutes to complete the exam will be :-
[using z-value table]
Hence, the probability that a randomly chosen student will take more than 30 minutes to complete the exam = 0.8413

<u><em>Explanation:</em></u>
<u>An isometry is</u> a transformation that preserves the size of the pre-image in the image and the corresponding angles and sides are also congruent.
<u>In each one of the images</u>, the figure given is he same size as the pre-image and The corresponding angles and corresponding sides are congruent; therefore they are all isometries. </span></span>
